The following analysis compares the frequency of selected first names across the various districts of Berlin. It was created using RMarkdown and Plotly and uses a dataset that can be found on the Berlin Open Data website here and is free to share and adapt under the following creative commons license.
The two chosen names are displayed on an interactive radar chart, which can be hovered over, zoomed-in on or selected to better understand the data. The names themselves can be changed by editing them within the RMarkdown file itself and re-knitting the html file. See the relevant lines here.
